The talk will present our recent results on development of multifunctional biocompatible nanoplatforms for cancer theranostics. The three nanoplatforms targeting tumors include polymeric nanoparticles (PNPs), nanoliposomes and protein nanocrystals; they can be equipped with NIR luminescence, photoacoustic (PA) and computed tomography (CT) imaging contrasts, along with PDT/PTT and chemotherapy modalities, which can be selectively activated by tumor microenvironment (TME). The talk will also demonstrate application of PNPs for visible or NIR fluorescence labeling of the systemically injected mesenchymal stem cells, which manifest tumor tropism in metastatic cancer animal model, allowing for fluorescence imaging based detection of primary tumor and metastases.
